About the Authors
FireRetardant.com content is created through a collaborative editorial process involving three core authors. Every article, guide, and resource published on this Website is reviewed, edited, and refined by all three contributors. This ensures that each piece of content benefits from practical field experience, scientific expertise, and modern digital communication standards.
No article is published without input from all three authors at some stage of the writing and review process. Each author contributes edits, clarifications, and fact-checking to maintain accuracy, clarity, and educational value.
Our Editorial Collaboration Model
Rather than assigning single authorship to individual articles, we operate as a unified editorial team. Content is drafted, reviewed, and revised collaboratively, with each author contributing their unique perspective:
- Practical fireground and safety experience
- Scientific and laboratory-based research interpretation
- Digital publishing, communication, and content structuring expertise
This process allows us to present information that is both technically informed and accessible to a general audience.
David MacKenzie
Role: Fire & Safety Operations Specialist
David MacKenzie is a retired senior firefighter and fire operations specialist from Victoria, British Columbia, where he served with the municipal fire service for just over 28 years. During his career, he progressed through multiple operational roles, including frontline suppression, crew supervision, and incident command support on complex structural and wildland-urban interface fires.
Much of David’s field experience was gained responding to high-risk incidents across Vancouver Island’s diverse environments, including dense residential neighbourhoods, coastal industrial zones, and forest-adjacent communities. His work regularly involved structural fire suppression, wildfire interface response coordination, confined space rescue support, and hazardous materials awareness-level operations.
Over the course of his service, David participated in numerous large-scale mutual aid responses across British Columbia, particularly during severe wildfire seasons where fire conditions placed significant pressure on municipal resources. These experiences shaped his practical understanding of fire behaviour, suppression strategy, and the real-world limitations of firefighting equipment and materials under extreme conditions.
David was raised in Nanaimo, British Columbia, in a working-class coastal community surrounded by forestry, marine transport, and small-scale industrial operations. From an early age, he was exposed to the realities of fire risk in resource-based environments, including logging camps, sawmills, and dockside operations. This background played a key role in developing his long-standing interest in fire dynamics and public safety systems.
Before joining the fire service, he completed technical training in emergency response and later pursued ongoing professional development in fire science, building construction awareness, and incident command systems. Even after retirement, he continues to stay informed on evolving fire suppression techniques and safety standards through professional associations and retired firefighter networks.
Outside of his professional life, David is an experienced salmon fisherman who spends significant time on the waters around Vancouver Island. He also has a long-standing interest in restoring vintage marine communication equipment, particularly analogue radios and navigation systems from mid-20th century fishing vessels. These hobbies reflect his lifelong connection to coastal life and maritime safety culture.
David is married to Linda, a retired school administrator who spent her career in the public education system supporting curriculum development and student services. Together they have two adult children: one working in environmental engineering and the other in paramedic services. Family life has remained closely tied to the Vancouver Island region, where they continue to reside.
In retirement, David remains actively engaged in community safety education initiatives. He volunteers with local emergency preparedness programs, occasionally delivers fire safety presentations to youth groups, and participates in mentorship activities for new emergency responders. His contributions to FireRetardant.com are grounded in decades of operational experience and a strong commitment to practical, real-world fire safety education.
Étienne Lavoie
Role: Scientific Research & Laboratory Analyst
Étienne Lavoie is a senior-level scientific researcher and laboratory analyst with extensive experience in materials science, chemical behaviour analysis, and fire-related safety research. Based for much of his professional life in Montreal, Quebec, he worked across both academic research environments and applied industrial laboratories focused on material performance under extreme conditions.
Étienne’s core areas of specialization include combustion byproduct analysis, thermal decomposition of synthetic and natural polymers, flame retardant material behaviour, and the evaluation of industrial safety compounds used in high-risk manufacturing environments. His work frequently involved controlled testing environments where materials were subjected to heat stress, ignition exposure, and chemical breakdown analysis to better understand real-world fire behaviour.
During Étienne’s career, he contributed to collaborative research projects involving university laboratories, private sector materials testing facilities, and regulatory advisory groups. His responsibilities often included designing experimental protocols, interpreting spectroscopic and thermal imaging data, and producing technical reports used to inform safety standards and product development in fire-resistant materials.
Étienne was raised in Sherbrooke, Quebec, in a bilingual French-English household where both academic discipline and scientific curiosity were strongly encouraged from an early age. His father worked in technical education, while his mother was involved in healthcare administration, creating an environment that valued both analytical thinking and public service. This upbringing played a significant role in shaping his methodical and research-driven approach to scientific inquiry.
He pursued advanced studies in chemistry and applied materials science at the university level, later focusing his graduate work on polymer stability and heat-induced molecular degradation. His early academic publications explored the structural response of synthetic materials under controlled combustion conditions, forming the foundation for his later applied research in fire safety materials.
Throughout Étienne’s career in Montreal, he became particularly interested in the intersection between theoretical chemistry and practical fire safety applications. This included evaluating how different material compositions influence flame spread, smoke toxicity, and residual structural integrity after exposure to high temperatures. His work helped bridge the gap between laboratory research and real-world fire prevention strategies.
Outside of his professional work, Étienne maintains a strong interest in classical music, particularly piano compositions from the Romantic and early Modern periods. He has played piano since childhood and continues to practice regularly as a form of focus and relaxation. He also enjoys hiking in the Laurentian Mountains, where he often reflects on scientific ideas in a quiet, natural environment.
In addition, he engages in small-scale woodworking projects, often building precise, functional items such as shelving units and custom storage pieces. This hands-on hobby reflects his appreciation for structure, measurement, and material behaviour in physical form.
Étienne is married to Claire, a medical laboratory technologist working in diagnostic pathology. Together they have one daughter, who is currently pursuing post-secondary studies in environmental science. Their household maintains a strong emphasis on education, research, and lifelong learning.
Étienne continues to stay actively engaged with peer-reviewed scientific literature, particularly in the fields of combustion chemistry, fire dynamics, and materials engineering. His contributions to FireRetardant.com are grounded in a rigorous scientific methodology, ensuring that all technical explanations are accurate, evidence-based, and aligned with current research standards.
